Abstract

Introduction: Although current evidence points to the possible prognostic value of electrocardiographic (ECG) findings for in-Hospital mortality of COVID-19 patients, most of these studies have been performed on a small sample size. In this study, our aim was to investigate the ECG changes as prognostic indicators of in-Hospital mortality. Methods: In a retrospective cohort study, the findings of the first and the second ECGs of COVID-19 patients were extracted and changes in the ECGs were examined. Any abnormal finding in the second ECG that wasn’ t present in the initial ECG at the time of admission was defined as an ECG change. ECGs were interpreted by a cardiologist and the prognostic value of abnormal ECG findings for in-Hospital mortality of COVID-19 patientswas evaluated usingmultivariate analysis and the report of the relative risk (RR). Results: Data of the ECGs recorded at the time of admission were extracted from the files of 893 patients; likewise, the second ECGs could be extracted from the records of 328 patients who had an initial ECG. The presence of sinus tachycardia (RR = 2. 342; p <0. 001), supraventricular arrhythmia (RR = 1. 688; p = 0. 001), ventricular arrhythmia (RR = 1. 854; p = 0. 011), interventricular conduction delays (RR = 1. 608; p = 0. 009), and abnormal R wave progression (RR = 1. 766; p = 0. 001) at the time of admission were independent prognostic factors for in-Hospital mortality. In the second ECG, sinus tachycardia (RR = 2. 222; p <0. 001), supraventricular arrhythmia (RR = 1. 632; p <0. 001), abnormal R wave progression (RR = 2. 151; p = 0. 009), and abnormal T wave (RR = 1. 590; p = 0. 001) were also independent prognostic factors of in-Hospital mortality. Moreover, by comparing the first and the second ECGs, it was found that the incidence of supraventricular arrhythmia (RR = 1. 973; p = 0. 005) and ST segment elevation/depression (RR = 2. 296; p <0. 001) during hospitalization (ECG novel changes) are two independent prognostic factors of in-Hospital mortality in COVID-19 patients. Conclusion: Due to the fact that using electrocardiographic data is easy and accessible and it is easy to continuously monitor patients with this tool, ECGs can be useful in identifying high-risk COVID-19 patients for mortality.
